Description
Technical field
The invention belongs to breaker of plastic casing technical field, relate to a kind of arc-control device for breaker of plastic casing and containing being somebody's turn to do
The chopper of device.
Background technology
Breaker of plastic casing when separating brake, due to moving contact and static contact from touch separate during, two contacts it
Between gap ascending, under high-tension effect, the dielectric in gap can be ionized and puncture, formed electric arc, electric arc shape
Cheng Hou, the heat of generation can be further exacerbated by medium ionization, expand electric arc, make the chopper cannot disconnecting circuit.In order to stop this
One process, designing chopper when, is contained in two contacts in one arc-chutes, has many passages inside arc-chutes, and one
Being used to subdividing the arc, two is the high pressure draught utilizing high arc temperature to produce, and blows out electric arc by the channel nozzle of arc-chutes.
The arc quenching principle of breaker of plastic casing mainly has following several: long arc arc quenching principle, short arc arc quenching principle and compound go
Ionic effect arc quenching principle.Generally, the arc-chutes of breaker of plastic casing use short arc arc quenching principle to be operated, this
Plant arc-chutes to have the disadvantage that
1, the vertically aligned arrangement of multiple arc extinguishing grid pieces in arc-chutes, moving contact when closing with static contact, away from
Nearest from arc extinguishing grid pieces, after moving contact fully opens, distance arc extinguishing grid pieces is farthest, therefore, when disjunction failed shorted electric current, dynamic
Contact also can be more and more remote from the distance that make position is gradually distance between static contact, and arc extinguishing grid pieces, and arc extinguishing grid pieces is topmost
Several just electric arc cannot be sucked, thus cannot subdividing the arc, reduce the effective rate of utilization of arc extinguishing grid pieces, electric arc is difficult simultaneously
To enter arc-chutes, make the breaking capacity of arc-chutes cannot meet requirement；
2, arc-chutes are open space, and during disjunction failed shorted electric current, the air-blowing that electric arc heated air produces divides to surrounding
Dissipate, cause arc extinguishing indoor gas to leak, be unfavorable for the extinguishing of electric arc, reduce disjunction effect；
3, direct current breaker of plastic casing is mostly to improve to form on the basis of exchange breaker of plastic casing, and it is disconnected that shell is moulded in exchange
The arc-chutes of road device cannot be used directly for direct current breaker of plastic casing, and arc quenching effect is poor.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of arc extinguishing efficiency high
Arc-control device for breaker of plastic casing and the chopper containing this device.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of arc-control device for breaker of plastic casing, this device includes base, the static contact that is arranged on base is with quiet
The suitable moving contact of contact, pair of parallel it is arranged on the sidewall of static contact both sides, multiple is arranged between two side and along dynamic
Arc extinguishing grid pieces that the motion camber line of contact is arranged in order and the arc-extinguish chamber being arranged on arc extinguishing grid pieces one end, described moving contact with
The electric arc produced between static contact is divided into short arc in arc extinguishing grid pieces, extinguishes the most rapidly.
Described moving contact is hinged with base, and described moving contact is around pin joint reciprocating rotation in vertical plane.
Described arc extinguishing grid pieces is arranged on the surface of static contact.
Described multiple arc extinguishing grid pieces are arranged in parallel.
Described arc-extinguish chamber includes the vertical parallel portion vertically arranging and being parallel to each other a pair, is arranged on and vertically puts down
The opening enlarging section of one end, row portion and be arranged on the vertical parallel portion other end and end plate that the sidewall with corresponding side is connected.Institute
Two the opening enlarging sections stated are horn-like setting, and two opening amplification units are less in one end spacing of vertical parallel portion, position
Relatively big in one end spacing of arc extinguishing grid pieces, beneficially air-blowing diffusion, make the air-blowing produced in breaking course enter together after converging
In arc extinguishing grid pieces, and utilize air-blowing that electric arc blows into arc extinguishing grid pieces, thus extinguish electric arc faster.
As preferred technical scheme, described end plate is perpendicular with sidewall.
It is provided with connecting plate between two described vertical parallel portion.Two vertical parallel portion are connected to one by this connecting plate
Rise.
The arc-extinguish chamber otch suitable with moving contact is offered on described connecting plate.This arc-extinguish chamber otch is prevented from working as
Moving contact is through connecting plate, and connected plate stops.
The described angle between two opening enlarging sections is 2-50 °.
A kind of chopper containing the described arc-control device for breaker of plastic casing.
The operation principle of the present invention is as follows:
When breaker of plastic casing separating brake, moving contact separates with static contact, and the electric arc produced between two contacts is inhaled into arc extinguishing
In grid, arc extinguishing grid pieces electric arc is divided into some segments (short arc), the arc extinguishing grid pieces of every segment is all formed a moon
Pole (cathode effect), between the most multiple arc extinguishing grid pieces, the accumulation of pressure drop makes total arc drop can reach cannot make electricity again
The degree of source voltage pilot arc burning, thus realize arc extinguishing.
Compared with prior art, the invention have the characteristics that:
1) multiple arc extinguishing grid pieces are to arrange along the camber line that moves of moving contact, it is possible to ensure no matter moving contact is in Guan Bi
State or off-state, all keep consistent with the distance between arc extinguishing grid pieces so that all of arc extinguishing grid pieces can obtain
Sufficiently utilize, jointly electric arc cut and cool down, it is thus possible to the electric current of disjunction failed shorted more quickly and effectively；
2) arc-extinguish chamber is used one end of arc-control device to be closed, the gas leakage in anti-locking apparatus, ensure that point simultaneously
During disconnected failed shorted electric current, the air-blowing that electric arc produces is moved in arc extinguishing grid pieces, and utilizes air-blowing that electric arc is blown into arc extinguishing grid pieces,
Thus extinguish electric arc faster；
3) arc extinguishing speed is fast, and arc quenching effect is good, is used not only for direct current breaker of plastic casing, can also directly apply simultaneously
In exchange breaker of plastic casing, and significantly improve the ability of its disjunction failed shorted electric current.
